clylinder and sleeve from the chamber E21 tirough the openings Q2 and thence is diftributed longitudinally by the annular grooves 25 and finds its outlet through the chamber lt and the longitudinal grooves 2() in the head block 17. buitablc connection, not shown in the drawing, may be provided between the oil chamber 21 and the interior 14 of each valve sleeve.

A piston rod25 is attached at one end to the piston 26 :md at its opposite end is attached to the crank shaft 27. Said crank shaft may be geared or coupled with the valve-operating shaft 28 in any suitable and suflicient manner. In the embodiment shown a sprocl'tet wheel 29 is carried on the crank shaft and a sprocket wheel 2() is carried on the cam shaft QB which are connected by the chain 3l. The cams 32 and 33 are carried on the shaft 28 in continuous contact with the valverods 19 and 19 att-ached to the sleeves, as hereinbefore described. Each of said v-alve rods is provided with a head 19 and 19", between which and the wall 34 are interposed the 'compression springs 35 and adapted to normally hold the heads 19 and 19 in contact with the faces of said cams. The construction thus described will reciprocate said sleeves in such timed relation to the reeiprocation of the piston. 26 as to alternately permit the intake of fuel and the exhaust of the products of the eX- plosion through the ends of the sleeves and the communiratin openings between the head of the cylinc er and the coperating sleeve. valves.

lt will be appreciated that'one ofthe cyl` inder sleeves will communicate with the manifold 3d While the other discharges into the atn'iosphere and that my sleeve valves thus described willl regulate the intake and discharge of fuel and products of combustion in 'perfect timed relation to the operation of the piston 26; that the spark plug is located in a position wherein no loss of power from the explosion occurs and that no possible loss of compression can he had from the explosion; and it will be further al'ipreciated that the` construction and relat1on of my valves with the cylinder' will la: likely to effect an economy in the amount oli fuel; that there will be less likelihood of the accumulation ot carbon resulting from the products of ex ilusion; that there will be no occasion for the grindingr of the valves to preserve compression and that deficient-.ies in engines of said chararter resulting from the use of puppet valves in the salienl points of their construction may be obviatcd by the valves of my construction wherein their aetion is more positive and diret-t.

Having thus described my invention, what l claim as nei' and desire to be secured by Letters Patent7 is:

ln an explosive engine, the combination with a cylinder and"a reciprocable piston carried therein', of a plurality of tubular valve chambers adjacent to said cylinder having a channel eonununieatiner between the explosion chamber in tbe cylinder and each of said sleeve chambers at right angles to' the pistons, a sleeve reriprorably carried in each of said valve chambers having an opening in its outer end. a blorlv removably carried in its inner end having longitudinal channels through same, a lubricant chamber located between said cylinder and valve chambers having openings into said valve chambers, a plurality of annular grooves surrounding said sleeves having orifices rommuni'catingwith the interior of the sleeve.,

wherebyr lubricant is communicated from the lubricant\chamber to the valve, chambers, distributed longitudinally by Vthe annular grooves and discharged through the orilires in the walls of the sleeves'and the channels in the end blocks` and means for alternately reciprocating Said sleeve valves in timed relation to the action of the piston. substantially as described.
